2.6.Statistical analyses
All the data obtained in the current study were analyzed in
accordance with a randomized complete block design using
the GLM procedure of SAS (SAS Inst.Inc.,Cary,NC).In Exp.1,
one-way analysis of variance test was used and when
significant differences (Pb0.05) were determined among
treatment means,they were separated by using Duncan's
multiple range tests.In Exp.2,the data were analyzed as a
2×2 factorial arrangement of treatments in randomized
complete block design.The main effects of probiotic products
(LF or SF),antibiotic (colistin or lincomycin),and their
interaction were determined by the Mixed procedures of SAS.
However,as the interaction (probiotic x antibiotic) was not
statistically significant (Pb0.05),it was removed from the
final model.The pen was the experimental unit for all analysis
in both experiments.The bacterial concentrations were
transformed (log) before statistical analysis.
3.1.Experiment 1
3.1.1.Growth performance and apparent total tract digestibility
Dietary treatments had no effect on the performance of
pigs during phase I (Table 3).However,during phase II and
the overall experimental period,improved (Pb0.05) ADG,
ADFI and G:F were observed in pigs fed PC,LF and SF diets
when compared with pigs fed NC diet.Moreover,pigs fed PC
and SF diets had higher (Pb0.05) ADG and better G:F than
pigs fed LF diet during phase II and the overall experimentalperiod.The dietary treatments had no influence on the ATTD
of DM and GE; however,pigs fed PC and SF diets had greater
ATTD of CP when compared with pigs fed NC and LF diets
(Table 4).
3.1.2.Bacterial population in faeces
Dietary treatments had no effect on the faecal total
anaerobes and Bifidobacterium spp.population at d 14 and
28,and Lactobacillus spp.at d 14 (Table 5).However,pigs fed
PC (d 14 and 28) and SF (d 28) diets had less (Pb0.05) faecal
Clostridium spp.and coliforms than pigs fed NC diet.
Moreover,pigs fed SF diet had greater (Pb0.05) faecal
Lactobacillus spp.population (d 28) than pigs fed NC,PC
and LF diets.
3.2.Experiment 2
3.2.1.Growth performance and apparent total tract digestibility
During phase I,pigs fed SF diet consumed more feed than
pigs fed LF diet,whereas the ADG and ADFI were similar
between pigs fed LF and SF diets (Table 6).During phase II
and the overall experimental period,pigs fed SF diet showed
better ADG (Pb0.01),ADFI (Pb0.01) and G:F (Pb0.05) thanpigs fed LF diet.However,different antibiotics had no effect
on the performance of pigs.Pigs fed SF diet had greater ATTD
of DM and CP during phases I and II (Pb0.01 and 0.001,
respectively) when compared with pigs fed LF diet (Table 7).
However,different antibiotics had no effect on the ATTD of
DM,CP and GE.
